In an early scene in HBO’s underrated horror series The Outsider, the would-be hero cop Ralph Anderson announces that he has no tolerance for the unexplainable. “Well then, sir,” Holly Gibney replies, looking ominously at the detectives through her eyelashes, “you’ll have no tolerance for me.” Holly (Cynthia Erivo) appears in several Stephen King novels, including 2018’s The Outsider, Mr. Mercedes, and its sequels.
